Which of the following is equivalent to the sum of
the expressions a² - 1 and a +1 ?

a^2 + a or a(a + 1).

Step-by-step explanation:

a^2 - 1 + a + 1

= a^2 + a - 1 + 1

= a^2 + a or a(a + 1).

they are simplified

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
